According to TVLine, Hahn will appear in multiple episodes of 'Parks and Rec' as a member of Leslie's opponent's political team. 'Parks' executive producer Mike Schur took to Twitter to correct the casting misinformation.

"Small point of clarity: Katherine Hahn is doing an arc on #ParksandRec, but she is *not* Leslie's opponent. We're thrilled to have her!" [sic]

Roughly 300,000 people voted on TV Guide Magazine's Facebook, and 'Community' bested many cult-hit shows including 'Chuck' and 'The Vampire Diaries.' The NBC series will be honored with three different covers for the Dec. 5 issue. The 'Community' issue hits newsstands Dec. 1.

"Because we don't get nominated for awards, this is our fans' outlet to tell us that they care," 'Community' star Gillian Jacobs said in a statement. "They may not see us win Emmys or SAG Awards, but they do have the power in something like this to vote, and you see a lot of people care about our show."

Ever since Piers Morgan quit the 'America's Got Talent' judging panel rumors have swirled about his possible replacement, and one name that keeps coming up is shock jock Howard Stern. He recently addressed the rumors and reiterated that he's a huge fan of the show, but wouldn't comment on whether he was involved in ongoing negotiations with NBC.

This week the 'New York Post' published a report alleging that Stern's agreed to join the show if certain conditions are met. Such as paying him a whopping $20 million and moving the show from Los Angeles to New York. The 'Post' quotes a source close to the show as saying that 'AGT' boss Simon Cowell is "hellbent" in landing Stern, and that "The talk on the production is that it's practically a done deal."

For his part, Cowell told 'Access Hollywood' that he's a fan of Stern but that nothing's been signed: "I like him. There's a lot of people who make decisions on this stuff. Money's got to work, schedules [have] got to work. There might be a few twists and turns still."

Jimmy Fallon apologized to Congresswoman Michele Bachmann Tuesday night for the fact that his 'Late Night' house band The Roots played a snippet of a 1985 Fishbone song called 'Lyin' Ass B*tch' as she was introduced on the show.

Bachmann accepted his apology but demanded one from NBC as well. Doing the rounds of TV and radio talk shows Wednesday Bachmann alleged that NBC's failure to act in the matter demonstrated that she was a victim "of bias from the Hollywood Entertainment elite."

Now the AP reports that the GOP Presidential candidate has received an apology from NBC. According to Bachmann's spokeswoman Alice Stewart, the network's vice president for late night programming, Doug Vaughan, wrote to her offering his most sincere apologies.

When Ava's show went on a forced production break for a week, it sounded like a great impromptu vacation for Reagan on 'Up All Night' (Wed., 8PM ET on NBC). She could kick back, relax and get to spend quality time with her baby. Sounds ideal!

Well not, apparently, if you're a bit of a control freak. When she's trying to make a smooth sailing ship out of the show, that keeps her occupied and apparently keeps her need to organize and make things "better" in check. Out of work, she's completely out of control.

In an interview with the Hollywood Reporter, Brown said an executive -- Edwin Chung, the senior vice president of primetime at NBC -- came to a 'Community' table read wearing his homemade T-shirt two days after NBC announced its plans to shelve the series.

"This is someone who's kind of in the process with us and knows that it's not ideal that we're not on the air," she said.

The 'Smash' goodies keep on coming! Hot on the heels of the new poster art, NBC has released the first official music video from the series, featuring Katharine McPhee covering Christina Aguilera's hit song 'Beautiful.'

In the pilot episode, McPhee's character Karen Cartwright auditions for a role in the new Marilyn Monroe musical with the song.

In addition to original shots, the video also features new footage from the show.

'Late Night With Jimmy Fallon' house band The Roots sparked controversy Monday night when, as guest Michele Bachmann was introduced, they played a snippet of a 1985 Fishbone song called 'Lyin' Ass B*tch.'

On Tuesday Bachmann's Democratic colleague, Congresswoman Nita Lowey (New York), protested the choice of song and issued a statement calling on NBC to apologize.

After Monday night's show Jimmy Fallon joked that bandleader Ahmir "Questlove" Thompson had been reprimanded, tweeting "@questlove is grounded." However, Tuesday night he went further and apologized: "I'm honored that @michelebachmann was on our show yesterday and I'm so sorry about the intro mess. I really hope she comes back."

Every time, I seem to lose track of the number of contestants somewhere in the middle of each season of 'The Biggest Loser' (Tue., 8PM ET on NBC). And then, all of a sudden there are only six or so people left in the house. That's where I found myself this week, surprised that it was so close to ending.

The contestants got to experience a little bit of Thanksgiving -- am I the only one who thinks of the absurdity of celebrating these holidays months in advance when the episodes were actually filmed? -- with a temptation challenge that promised three different prizes.

Well, we were right: The ax-wielders over at NBC have decided to give fledgling drama 'Grimm' time to find its feet and develop an audience. 'Entertainment Weekly' reports that the network has placed a full series order, making 'Grimm' the only new NBC hour-long series to get a "back nine" episode order this fall.

NBC President, Robert Greenblatt, said "We are very pleased to be making a full-season commitment for 'Grimm.' This series is turning the traditional procedural drama on its head and is attracting a loyal following for us on Friday nights. We love where it's going creatively and we're excited to deliver more episodes to our audience."

In anticipation of next week's live finale, the phone lines opened for the first and last time on this longest-ever season of 'The Sing-Off' (Mon., 9PM ET on NBC). But before fans could decide who should win this season, the competition had to lose one final act.

It was a brutal night to be facing elimination, so close to the final, and you could see nerves throughout the evening as no one had a flawless night. Nevertheless, the judges based their decisions on what we've seen all season long, including tonight's double bill of a mastermix combining two songs and a judges' choice song.

It looks like NBC is far more enthusiastic about 'Up All Night' than viewers are. The Peacock network has ordered two more episodes of the freshman comedy, bringing its total number up to 24 for the season, Deadline reports.

The Will Arnett/Christina Applegate comedy has been a modest performer for NBC (a recent episode scored 4.8 million viewers and a 1.9 in the adults 18-49 demo) but compared to the rest of NBC's floundering schedule, consistency in the ratings is probably an attractive prospect right now.

The move is the latest vote of confidence for the show, which is being moved from Wednesdays at 8.30PM ET -- where it currently goes up against 'X Factor,' 'Survivor' and 'Suburgatory' -- to 9.30PM on Thursdays, where it will have 'The Office' as a lead-in, starting Jan. 12.
